Sorry, don't know the size but if the plugs have been changed you may have a size smaller. Champion plugs take a smaller socket than the org. plugs.:waving:Keno

Thanks for the info by the way,the clymer manual doesn't seem to say nor does the owners manual.

3/4" is almost exactly 19 millimeters. 19,05 to be precise. The most common spark plug dimensions are 13/16 and 11/16". And for chainsaws and other small engines 3/4". Almost all Honda cars after 1983 have 11/16, those before that have 13/16".:readit:
11/16 is 17,46mm and 13/16" is 20,637 mm....

Yes, I know. This is a motorcycle forum.:ROFL:

close but no cigar. 19mm and 3/4 are usually considered interchangeable. My Snap-on 3/4 has stamped on it " 3/4 19mm"

As for 11/16 that is what my Honda Civic and GL1200's use. Normally11/16 is considered a practical interchange with 17mm but only my 18mm fits.
